Agree. The GPU hardware needed to do the compositing and simple effects that you see in typical desktop environments is trivial. You're talking about literally 100's of polys and extremely simple shaders.
Except, due to how Win7's clip regions affect compositing, if you have Windows open underneath the Windows you are using, they still affect the clip regions, and apps such as Skype, when they update the video Window, have to split up those updates per each clip region. What happens in practice, is that you get severe tearing, with part of the Window updating before the other part.
I found that an NV GT430 card in my Gateway slimline G630 rig, greatly reduced the affect of this window clip-region tearing during Skype calls, compared to the HD2000 IGP in the Sandy Bridge Pentium CPU.
So, in my particular case, inachu is correct. Sandy Bridge HD2000 IGP is NOT powerful enough for desktop purposes, particularly Skype.
